How much can you earn from home charging?

Earning money with your own charger has been possible since 1 January 2026: for every kWh that goes into the electric car at home, a piece of ERE credit is created. Your registration partner sells those emission reduction units at a market price.

What Joulo actually realised: €0.129 net per kWh. That comes from the sale of 23 July 2026 at €0.483 per ERE, at the standard 20% service fee. It is a realised, contracted sale price • not a reference price and not a forecast. Every sale is published with its date, volume, broker and price per ERE in the open sales ledger.

If you prefer an average: the average ERE payout in 2026 is €0.12–€0.15 net per kWh, depending on the ERE market price at the moment of sale and your registration partner's service fee.

A note on comparisons: most comparisons assume one single market price for every provider and then only weigh the service fee against it. Your net payout actually depends on two things: the price your registration partner genuinely realises, and the percentage deducted from it. So ask for realised sale prices, not just for the percentage.

Two prerequisites

1. Your charger has a MID-certified meter. Without one, sessions are not reliable enough to register. A MID meter inside the charger's own enclosure is sufficient • even if the charger itself is not type-approved. Check your model with the charger check. 2. The energy contract behind the charger is in your name. The payout goes to the person or organisation holding that contract.

Official NEa formula (2026)

The number of ERE credits is calculated automatically in the Energy for Transport Registry (REV). The formula for grid electricity is:

kWh × 0.505 × 183 × 3.6 / 1000

Where 183 g/MJ is the fossil reference value and 3.6 MJ/kWh is the conversion factor. Factor 0.505 is the renewable share of the Dutch electricity mix (CBS 2024, applies to 2026). For consumers this grid average always applies, regardless of own solar panels.

Three factors determine your earnings

1. How many kWh you charge per year through your charger 2. The price your registration partner realises when selling the ERE credits • at Joulo €0.483 per ERE on 23 July 2026, see the sales ledger 3. The service fee of your registration partner • compare all providers

Important: The EAN code of the connection in the Central Connections Register (CAR) determines who is entitled to the payout. That is not always the driver of the car, but usually the owner or tenant of the location. If you drive a lease car, the payout goes to the resident holding the energy contract, not to the leasing company.
